The three-dimensional structure of Saturn's E ring
, 2012 Saturn's diffuse E ring consists of many tiny (micron and sub-micron) grains of water ice distributed between the orbits of Mimas and Titan. Various gravitational and non-gravitational forces perturb these particles' orbits, causing the ring's local ...

Slantwise Convection and Heat Transport in Icy Moon Oceans
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Ocean heat transport on icy moons shapes the ice shell topography, a primary observable of these moons. Two key processes control the heat transport: baroclinic instability driven by surface buoyancy contrasts and convective instability driven by heating from the core.

Geysers' Dust Dynamics Inside the Hill Sphere of Enceladus
Geophysical Research LettersIn this work, we study the trajectories of the dust particles ejected in the geysers of the moon Enceladus, inside its Hill sphere, where its gravitational influence dominates. Our goal is to determine the properties of the particles that escape from the

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract In Saturn's magnetosphere, the inward transport of magnetic flux is largely carried by localized injection flux tubes filled with warm, tenuous plasma, although their inflow speeds and spatio‐temporal properties remain poorly constrained. Here, we propose that these flux tubes can modify electron microsignatures, the small‐scale, absorption ...

Is Enceladus' plume tidally controlled?
Geophysical Research Letters, 2008 Explanations for the plume of gas, water vapor and ice particles jetting from rifts in Enceladus' south polar region include boiling of liquid water and dissociation of clathrate hydrates.

Geophysical Research Letters, 2009 Near infrared spectra of the surface of Enceladus returned by Cassini show the presence of an absorption feature at 3.53 μm, ascribed by Brown et al. (2006) to “short chain organics,” and by Newman et al. (2007) to hydrogen peroxide. We assign this feature tentatively to methanol.

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Saturn's inner magnetosphere contains a weak antisunward electric field that has influenced a wide array of different aspects of the magnetospheric conditions in that region. Previously, these currents have been explained as being caused by magnetospheric drivers.

The Effect of Salinity on Ocean Circulation and Ice–Ocean Interaction on Enceladus
The Planetary Science JournalObservational data suggest that the ice shell on Enceladus is thicker at the equator than at the pole, indicating an equator-to-pole ice flow. If the ice shell is in an equilibrium state, the mass transport of the ice flow must be balanced by the ...

A Recent Impact Origin of Saturn’s Rings and Mid-sized Moons
The Astrophysical Journal, 2023 We simulate the collision of precursor icy moons analogous to Dione and Rhea as a possible origin for Saturn’s remarkably young rings. Such an event could have been triggered a few hundred million years ago by resonant instabilities in a previous ...

Tidal pattern instabilities on multi-moon planets [PDF]
, 2007 The equilibrium tide-generating forces in the lunar orbital plane of a planet of radius R are calculated for the case of N moons of mass M_i orbiting the planet at instantaneous polar coordinates (D_i, \alpha_i).
